2003 Suburban 1500 dual climate control problem
My problem appears to be different from most on here. On auto the passenger side thermostat works correctly but the driver side wont turn up past 69 degrees. if I keep turning it up it gets to 69 then starts to turn down. If i do it on degree then wait a few minutes and turn it up 1 more degree then repeat process sometimes I can get it to as high as 71 before it jumps back to 65. Any ideas what I need to do to fix it. This is my wife's everyday driver and she is tired of being cold.
